S235JR ist der entry-level structural steel in der EN 10025 standard family, directly comparable zu der former German St37-2 designation. Mit 235 MPa minimum yield strength, es ist specified für allgemein construction, non-kritisch welded structures, und sekundär framing wo strength requirements sind modest. Excellent formability für kalt bending und folding, gut galvanizing response, und straightforward welding mit E6013/E7018 electrodes. Der JR grade guarantees 27 Joules impact energy bei +20°C, suitable für indoor und temperate-climate outdoor structures.

Frequently Asked Questions
Ist S235JR noch commonly used in modern construction?
S235JR ist increasingly seiend replaced durch S275JR in primär structural applications due zu S275's 17% higher strength bei minimal kosten premium. However, S235 remains widely used für sekundär members (purlins, girts, bracing), non-structural steel (handrails, staircases, grating), und applications wo stiffness rather als strength governs der design. Sein excellent kalt formability auch makes es preferred für complex folded plate und kalt-formed steel sections.
